Embodiment Construction
[0024] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.
[0025] Such as figure 1 As shown, the open bioreactor for microalgae cultivation of the present invention includes: reactor 1, gas-liquid mass transfer device 2, microalgae harvesting system 4, algae liquid return system 5, microalgae concentration detector 6, pump 7. As well as flow meters, control valves, etc. in:
[0026] The reactor 1 is flat and is arranged outdoors, such as figure 2 As shown, the reactor 1 can be installed obliquely, and the angle α between its bottom surface and the horizontal plane is in the range of 0 to 1 degree, which is specifically set according to the growth time required by different algae species, and the effect of gravity is used to make it The algae liquid in the reactor 1 forms a smooth flow; or, the reactor 1 is placed horizontally, and a fluid forming device such as a centrifugal pump and other liquid power...

The invention discloses an open bioreactor for microalgae cultivation and a cultivation method thereof. The bioreactor includes a reactor (1) arranged outdoors, a gas-liquid mass transfer device (2), and a microalgae harvesting device. System (4) and algae liquid reflux system (5), described reactor (1) is flat plate, through the upstream end of the algae liquid input reactor (1) of gas-liquid exchange with carbon dioxide to keep steady flow to the downstream end so that micro The algae grow along the flow direction of the reactor, and after reaching the downstream end of the reactor (1), when the algae body reaches the required concentration, the microalgae harvesting system (4) harvests and separates the microalgae, and when the required concentration is not reached, it passes through the algae liquid return system (5) transport back to the gas-liquid mass transfer device (2). The open bioreactor for microalgae cultivation and the cultivation method thereof of the present invention are not only low in cost, easy to maintain and maintain, and are not easy to be polluted by foreign microalgae for characteristic algae species, and have high carbon dioxide utilization rate, and are suitable for large-scale and low-cost Farming microalgae.
Description
technical field [0001] The invention relates to a reactor used for microalgae cultivation and a cultivation method using the reactor, in particular to a bioreactor for outdoor cultivation of microalgae and a cultivation method thereof. Background technique [0002] There are two main types of traditional microalgae cultivation reactors: closed reactors and open reactors. Closed reactors mainly include tubular reactors, vertical plate reactors, bag reactors, and stirred tanks. Closed reactors are not easy to pollute during the breeding process, and the concentration of algae in the water is high. The algae breeding process is easy to control, but the closed reactor also has the following disadvantages: 1. Because the algae liquid is affected by light and absorbs a lot of heat, the internal temperature of the reactor rises, so the breeding process requires a lot of heat exchange equipment; 2. Closed reaction The reactor usually needs to be equipped with an artificial lighting...
